Hi,
yes we know about this, the docu is built in an automatic upstream process when the according version is built. If you change the docu version to nightly (in the left bottom where it says v.6.2.1707) you can see the updated version. We wanted to avoid intercepting this automated progress and because of this the docu will be updated with the 1708 release. Actually we need to put that information somewhere visible on the homepage and on sourceforge, but a lot of people are on holiday right now so things need a bit at the moment
But thanks for pointing it out.
Best
Christopher
